All of the cradle-to-grave studies I've seen about greenhouse gas emissions for renewables versus coal/oil still indicate massive improvements.

This government meta study of 3,000 such studies puts PV solar at roughly 20x less emissions than coal.

Yes, but you're missing the point, I'm not debating that. Renewables aren't free, we should care about consumption just as much as production, and we don't know (yet) how to sustain the current consumption with renewables only, that includes being able to manufacture renewables.
